A connector for communications systems has four input terminals and four output terminals, each arranged in an ordered array. A circuit electrically couples each input terminal to the respective output terminal and cancels crosstalk induced across the adjacent connector terminals. The circuit includes four conductive paths between the respective pairs of terminals. The first and third paths are in relatively close proximity and are substantially spaced from the second and fourth paths. The second and fourth paths are in relatively close proximity.

An adapter for coupling electrical connectors has a housing having first and second connections on first and second opposite ends of the housing. A set of electrical contacts extends in each connection. A first connector can be coupled to the first connection and can electrically engage its electrical contacts. A circuit is mounted in the housing for electrically connecting the contacts. A latch is attached to the first connection for releasably securing the first connector to the first connection. A release is coupled to the latch and is accessible for operation at the second end of the housing for unlatching the first connection from the first connector.

A switch cover plate assembly includes label covers each having an elongated main portion and a pair of opposite ends and a switch faceplate for mounting the label covers. The faceplate has a flat main panel, switch holes therethrough adapted to receive switch actuators, mounting holes therethrough adapted to receive therethrough fasteners to mount the faceplate to a switch box, and label cover mounting recesses and a pair of slots defined at opposite ends of each of the mounting recesses. Each mounting recess and pair of mounting slots are adapted to receive and mount one of the label covers. Each label cover is adapted to seat within one mounting recess and to be slidably insertable into and removable from the mounting slots. A pair of parallel opposite edge surfaces are defined on opposite sides of the mounting slots at inclined angles to the plane of the flat main panel so as to extend along and parallel to a path through which the opposite end portions of the label cover must slidably move in order to insert into and withdraw from the mounting slots. Each mounting hole is defined through the flat main plate in one of the mounting recesses and spaced from the mounting slots of the pair thereof defined at the opposite ends of the mounting recess. Also, each label cover also includes grooves defined in the main portion adjacent to opposite end portions of the respective label cover to permit insertion and engagement of an object, such as a fingernail, within the groove of the label cover in order to slidably move the label cover relative to the faceplate and into and from the mounting slots.

An electrical connector has a modular nose or modular noses. The modular nose can be interlocked with the housing or can be interlocked with other noses and the housing or only with other noses. The interlocking is provided by projections extending laterally from opposite sides of the nose. These projections engage correspondingly shaped notches in adjacent noses or in adjacent portions of housings.

A nonmetallic conduit fitting having first and second tubular members rotatably coupled about a transverse axis of rotation allowing the fitting to be used in a straight or in angled positions. The first tubular member has a plurality of latching tabs with each latching tab having a first surface that rotatably and slidably engages a second surface on a flange extending from the second tubular member via a snap fit. The first surfaces of the latching tabs and the second surface of the flange define a plane of rotation therebetween which is substantially perpendicular to the axis of rotation. In the first embodiment, the latching tabs of the first tubular member engage an inwardly extending flange on the second tubular member via a snap fit. Abutment members are provided on the inwardly extending flange for engaging the gaps between the latching tabs to selectively retain the first and second tubular members in a straight or angled position. In the second embodiment, the first tubular member includes an annular wall having a plurality of latching tabs that engage an outwardly extending flange of the second tubular member via a snap fit. An abutment member on the first tubular member engages notches formed on the peripheral surface of the outwardly extending flange for selectively retaining the first and second tubular members in a straight or angled position.

A duct assembly for enclosing conduits, cables, wires, lines and the like, comprising a base having a generally U-shaped cross section along its longitudinal axis, and a cover having a generally U-shaped cross section along its longitudinal axis. The base includes a generally planar central portion with first and second legs extending substantially perpendicular thereto. The cover includes an intermediate portion having third and fourth legs extending substantially perpendicular thereto. The cover is pivotally and releasably coupled to the base at one end and releasably coupled to the base at the other end. The pivotal and releasable coupling is made up and released via a snap fit resulting from forces exerted substantially perpendicular to the longitudinal axes of the cover and the base. The pivotal coupling allows angular movement of the cover relative to the base through about 45.degree. to about 60.degree..
